Android的前置摄像头的prevent翻转 [英] Prevent Flipping of the Android Front Facing Camera

问题描述

我试图访​​问Android的前置摄像头的新进料。默认情况下，前置摄像头的preVIEW的水平翻转，使用户可以看到自己仿佛在寻找到了镜子 - 这是伟大的，但不是我所需要的。什么是让新进料的最佳方法是什么？有没有一些方法来禁用自动翻转，或者我应该试图甩掉它在code自己（如果有的话，什么是这样做的最佳方式）？为了清楚起见，我的应用程序需要显示的前置摄像头的实时反馈，而不必让翻转像一面镜子。

I'm attempting to access the raw feed of android's front facing camera. By default, the front facing camera's preview is flipped horizontally so users can see themselves as if looking into a mirror - that's great, but not what I need. What's the best way to get the raw feed? Is there some way to disable the automatic flipping, or should I attempt to flip it in code myself (and if so, what's the best way to do so)? For clarity, my application needs to display a real-time feed of the front facing camera without it being flipped like a mirror.

推荐答案

如果你想使用一个前置摄像头的吧code扫描您可以使用TextureView和应用转换矩阵它。当结构是更新可以读出的图像数据，并使用该

If you want to use a front-facing camera for barcode scanning you can use TextureView and apply a transformation matrix to it. When the texture is updated you can read the image data and use that.

具体从MainActivity.java

Specifically from MainActivity.java

mCamera.setDisplayOrientation(90);
Matrix matrix = new Matrix();
matrix.setScale(-1, 1);
matrix.postTranslate(width, 0);
mTextureView.setTransform(matrix);
